To alla/.hom it may-concern.-

Be it known that I, MILTON F. WILLIAMS,

of the city of St. Louis, State of Missouri,have

invented certain new and useful Improvements in Disintegrators or Crushers, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming apart hereof.

My invention relates to an improved disintegrator or crusher; and it consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed. Y

In the drawings, Figure lis a top plan View of my improved disintegrator or crusher. Fig. 2 is a cross-sectional view taken approximatelyon the indicated line 2 2 of Fig. 1. Fig. 3 is a transverse sectional View taken approximately on the indicated line 3 3 of Fig. 1.

Referring by numerals to the accompanying drawings, 1 indicates a suitable rectangular framework that is held together at the ends by suitable tie-rods 2. Located upon the top surfaces of the two side rails of this framework 1 and in alignment with each other are journal-bearings 3. Mounted for rotation in these j ournal-bearin gs 3 is a shaft 4, the ends of which -proj ect slightly beyond said journalbearings. On one end of said shaft is located a iiy-wheel 5, and upon the opposite end of said shaftis located a belt-wheel or pulley 6.

Located within the frame 1, beneath the shaft 4, is a rectangular metallic box 7, the same being providedl with laterally-projecting perforated ears 8, that are bolted to the side rails' of the frame l, thereby rigidly securing in proper position said metallic box 7.

This box`7 is provided on its front end with an integral hopper 9, and the lower edges of the walls of this box 7 are provided with an inwardly-projecting flange or lip, as indicated by the numeral 10, and in said walts, closely or openings 1l, and said bars or slats 13 are rigidly held in said slots or openings and in proper position by means of headed screw- Abolts-14 that pass upwardly through the ange or lip 10 formed integral with the lower edges of the box 7. Fixed to said box in any suitable manner and depending therefrom is a dischargespout 15. y

Rigidly mounted upon the shaft 4 within the box 7 are a series of disks 16, the peripheries of which travel in a path `iust above the horizontal plane occupied by the top edges of the bars 13. These disks are held at equal distances apart by interposing equalsized washers or rings 16a between said disks and upon thefsh'aft 4. Loosely pivoted upon bolts 1Gb, that pass longitudinally through the entire series of disks 16, are a series of short metallic bars 17, the same performing the function of hammers, and said metallic bars 17 while in movement pass between the transversely-positioned bars or slats 13.

The operation is as follows: A belt is passed over the pulley 6, and said pulley is rotated at a very high rate of' speed in the direction of the arrow A, Fig. 2. Consequently the shaft 4, upon which said pulley is rigidly fixed, and the disks 16, which are mounted upon said shaft 4, will be rotated at arate of speed equal to the speed of the driven pulley 6. According to the well-knownlaws of centrifugal vaction the bars 17 will, as -soon the disks to and between which they are pivoted-attain a certain speed, be carried or thrown outwardly and into lines radiating fromvthe center of the shaft 4. The rock, coal, clay, or other product to be crushed or disintegrated is fed in through the hopper 9 to the interior of the metallic box 7. As soon as it enters said box it will be forcibly struck successively by-the rapidly-moving bars 17 and disintegrated or crushed in the desired manner. Said product will be carried around on the inner side of the semicircular top 12 of the casing and fall or gravitate onto the bars or slats 13, and said product will be further crushed or disintegrated until itis line enough to vpass through between said bars or slats. If the product on being first fed through the chute or hopper 9 resists the IOO blows of the rapidly-moving bars 17, said bars will move inwardly toward the shaft 4L and pass by said product MThus the pivoted bars 17 are made' toperforin the function of hammersin disintegratin'gor crushing the product, as said bars when moving at a very high rate of speed strike a blow in every way similar to a blow of the hammer. 'The positions occupied by these bars 17 when the shaft 4 is at rest are clearly indicated by solid lines in Fig. 2, while the positions they occupy when the disk is highly rotated and said bars are thrown outwardly by centrifugal action are clearly shown by dotted lines in Fig. 2.

Assumingr that the shaft 4 is rotated at a speed approximating three hundred revolutions per minute, if there be six bars, such as 17, mounted upon each one of the disks, there will necessarily be approximately eighteen hundred blows struck per minute by the bars carried by each disk, and this action will not fail to crush or disintegrate in the manner desired any product that may be passed through a machine of the class described.

A disintegrator or crusher of the class described is especially adapted for use in disintegrating coal, clay, shale, &c.,though it may be advantageously used for crushing or disiutegrating orebearing rock, &c.

By constructing the slots or apertures 11 slightly wider than the bars 13, the degree of neness to which the product may be crushed or disintegrated may be regulated.

The improved disintegrator or crusher, comprising a suitable frame,a plurality of annular-series of rotary hammers supported by said frame and each series spaced a distance apart, a rectangular metallic box 7 supported by said frame and having at its lower edges an inwardlyprojecting flange or lip 10, the opposite walls of said box at points adjacent said lower edges having formed in them a series of rectangular slots 11, a suitable cover and hopper for said box, a series of metallic bars or slats 13 extending across the said box and having their ends loosely mounted in said slots, and screw-bolts 14 passed upwardly through said flange or lip into engagement with said bars or slats, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
